Installing V7 on 64-bit XP turned out to be a real challenge, mostly due to Microsoft's .NET 2.0 Framework (which I did not previously have on my system). Thank goodness I had Acronis on my system to rescue me when needed. But if you do it right, Vegas does install just fine on this platform.
Vegas's installer kicks off the install of .NET Framework 2.0. Unfortunately it downloads the 32-bit version (only) which then starts installing and then fails. So I went to the Windows Update site and downloaded the 64-bit version. This failed too. I rebooted my computer. Then I learned that ALL my .NET Framework stuff was corrupted, and my existing Vegas 6 wouldn't run either. Attempts to uninstall/reinstall or repair the .NET framework all failed.
Fortunately I have Acronis on my system, and I had a backup from August 28th. So I restored the system partition and rebooted. Vegas 6 loaded, but when I fired up a project it complained that 5 audio plugins (standard ones that came with Vegas) are not installed properly. So I fired up Acronis again and restored the Vegas 6 folders plus the "common" plugin folders, etc. This got me back to where I was before I started. No problem, just a lot of headaches.
To make a long story short, I DID find a successful way to upgrade to Vegas 7 on my 64-bit system. Here's what I did. This procedure should work for all 64-bit users, but it's also a good idea for 32-bit XP users.
1) Do a full system backup. Best practice is to have your OS on its own partition.
2) Go to Microsoft's download site and download the 64-bit version of the .NET Framework 2.0. Don't install it just yet...
3) Go to Administrative Tools -> Services. Disable the Anti-virus services (don't just stop them, actually disable them). Disable other programs that use .NET (such as the ATI video driver control panel)
4) Reboot. When the system boots, your antivirus will be off.
5) Install the .NET Framework 2.0 that you downloaded (NOT the one that Vegas launches)
6) Reboot. (Your PC might not ask you to do this, but you MUST. In the Windows event log I saw a message saying .NET commanded a restart, but nothing actually happened. So I did it myself)
7) On reboot, your antivirus will still be disabled. That's good. Now you can install Sony Vegas 7 (and Media Manager).
8) SUCCESS!!! Now you can go back to the services and restore the Antivirus programs to "Automatic" instead of "Disabled"
I found that my VSTs and a few other plugins were not working on V7. I probably just need to reinstall them.
